Although THs and FHs do not appear to view dementia as a specific disease, they may provide a means of identifying people with dementia in this setting.
The care needs of PwP are considerable. To reduce carer strain and improve quality of life, carers' needs must be considered to enable them to carry on with their vital role.
Objectives: To investigate whether people with Parkinson's disease can exercise at a high-intensity across a 12-week intervention and to assess the impact of the intervention on cardiorespiratory fitness. Design: This is a randomized, controlled, feasibility study with waiting list control. Assessors were blinded to group allocation. Setting: The intervention took place at an exercise centre and assessments at a district general hospital. Subjects: This study included 20 people with idiopathic Parkinson's disease. Intervention: A total of 36 exercise sessions over 12 weeks, with each session lasting ~45 minutes, were conducted. Main measures: The main measures were maximal heart rates achieved during exercise, recruitment rate, attendance, drop-out, change in peak oxygen consumption, cardiac output, cognitive function and quality of life. The study was considered technically feasible if participants achieved ⩾85% of maximal heart rate during exercise. Results: There were 12 male and 8 female participants; they had a mean age of 68.5 years (standard deviation 6.825). Two participants were of Hoehn and Yahr stage I, 11 stage II and 7 stage III. In all, 17 participants completed the intervention. The median (interquartile range) proportion of repetitions delivered across the intervention which met our high-intensity criterion was 80% (67% to 84%). Mean peak heart rate was 88.8% of maximal. Peak oxygen consumption increased by 2.8 mL kg −1 min −1 in the intervention group and 1.5 mL kg −1 min −1 in the control group after 12 weeks of exercise. We estimate that a fully powered randomized controlled trial would require 30 participants per group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
